| | 28 Mar 2022 | 20:49 PDT | Summary On Friday, 18 March 2022 at 15:20 US/Pacific, Google Cloud Networking experienced intermittent packet loss for traffic between multiple cloud regions for a duration of 8 minutes. The issue was identified and mitigated automatically by 15:28 US/Pacific. We understand this issue has affected our valued customers and users, and we apologize to those who were affected. Root Cause Google’s production backbone is a global network that enables connectivity for all user-facing traffic via Points of Presence (POPs) or internet exchanges. A rare hardware failure of a component on the fiber paths from one of the transpacific gateway campuses in Google’s production backbone led to a decrease in available network bandwidth between the gateway and multiple edge locations, causing packet loss. Remediation and Prevention Google’s automated repair mechanisms detected the decrease in available network bandwidth on Friday, 18 March 2022 at 15:20 US/Pacific and automatically routed the traffic through alternate links. The traffic rerouting completed on Friday, 18 March 2022 at 15:28 US/Pacific, mitigating the issue. While our automated mechanisms worked as intended and recovered the traffic without manual intervention, we understand that the scope of impact caused by this rare event affected our customers. We have been working on optimizing our global network to minimize the time spent automatically reconfiguring around failures like this (known as "convergence time"). While we have made progress, efforts to improve still further remain ongoing. We continue to ensure that the current technology is optimally configured to minimize the frequency and severity of these issues. Google is committed to quickly and continually improving our technology and operations to prevent service disruptions. We appreciate your patience and apologize again for the impact to your organization. We thank you for your business. Detailed Description of Impact Customers may have observed packet loss for traffic routed via transpacific links on Google's backbone. This could include traffic from or to any of the following cloud regions:
